Suitable reagents include ammonium formate, ammonium acetate, ammonium carbonate, and ammonium chloride/ammonium hydroxide. Other conventional sources of ammonia may be used.
By way of illustration, ammonium formate is used as the ammonia source. Thus, reaction (1) is conducted by combining approximately equimolar amounts of II, III and IV in solvent. Although the reactants may be added in any order, it is preferred to add IV to a stirred solution of II and III in solvent. Reactant (II) may be prepared in situ from formic acid. Suitable solvents include water. The reaction is conducted at a temperature of about 0°C to about 50°C, preferably from about 5°C to about 30°C, and is generally complete within about 1 to about 4 hours. The product V is isolated by oonventional procedures suoh as extraction, distillation, column chromatography and the like. Alternatively, V may be isolated as a salt, such as the hydrochloride, by precipitation.
Reaction (2) is conducted by combining approximately equimolar amounts of V, VI and VII in solvent. Although the reactants may be combined in another order, it is preferred to add VII to a stirred mixture of V and VI in solvent. Certain examples of V, or its salts are commercially available and may be used rather than preparing V according to Reaction (1). Although approximately equimolar amounts of V, VI and VII may be used, it is preferred to use a slight excess of VI in relation to V and VII, on the order of about 1.1 to about 1.2 equivalents VI per equivalent of V/VII. Suitable bases include organic bases such as triethylamine, pyridine, and the like or inorganic bases, such as sodium hydroxide, potassium hydroxide or the like. Suitable solvents include inert organic solvents such as methylene chloride, chloroform, benzene, or the like, and water.

Utility
The compounds of the present invention are useful in controlling a wide variety of pests.
These compounds are active as fungicides and are particularly effective in controlling a variety of fungi which are deleterious to plants, including plant fungal infections. These compounds are particularly effective in controlling certain leaf blights caused by organisms such as Phytophthora infestans. In addition, some of these compounds are useful in controlling blights caused by organisms such as Alternaria solani and Septoria apii, rice blast caused by the organism Piricularia oryzae and powdery mildews such as that caused by Erisiphe polygoni. However, some of the compounds of this invention may be more fungicidally active than others against particular fungi.
In addition, some of the compounds of this invention show antibacterial activity and may inhibit bacterial growth.
When used as fungicides, the compounds of the invention are applied in fungicidally effective amounts to fungi and/or their habitats, such as vegetative hosts and non-vegetative hosts, e.g., animal products. The amount used will, of course, depend on several factors such as the host, the type of fungus, and the particular compound of the invention. As with most pesticidal compounds, the fungicides of the invention are not usually applied full strength, but are generally incorporated with conventional, biologically inert extenders or carriers normally employed for facilitating dispersion of active fungicidal compounds, recognizing that the formulation and mode of application may affect the activity of the fungicide. Thus, the fungicides of the invention may be formulated and applied as granules, as powdery dusts, as wettable powders, as emulsifiable concentrates, as solutions, or as any of several other known types of formulations, depending on the desired mode of application.
Wettable powders are in the form of finely divided particles which disperse readily in water or other dispersants. These compositions normally contain from about 5% to 80% fungicide, and the rest inert material, which include dispersing agents, emulsifying agents and wetting agents. The powder may be applied to the soil as a dry dust, or preferably as a suspension in water. Typical carriers include fuller's earth, kaolin clays, silicas, and other highly absorbent, readily wettable, inorganic diluents. Typical wetting, dispersing or emulsifying agents include, for example: the aryl and alkylaryl sulfonates and their sodium salts; alkylamide sulfonates, including fatty methyl taurides; alkylaryl polyether alcohols, sulfated higher alcohols and polyvinyl alcohols; polyethylene oxides; sulfonated animal and vegetable oils; sulfonated petroleum oils; fatty acid esters of polyhydric alcohols and the ethylene oxide addition products of such esters; and the addition products of long-chain mercaptans and ethylene oxide. Many other types of useful surface-active agents are available in commerce. The surface-active agent, when used, normally comprises from 1% to 15% by weight of the fungicidal composition.
Dusts are freely flowing admixtures of the active fungicide with finely divided solids such as talc, natural clays, kieselguhr, pyrophyllite, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulfur, lime, flours, and other organic and inorganic solids which act as dispersants and carriers for the toxicant. These finely divided solids have an average particle size of less than about 50 microns. A typical dust formulation useful herein contains 75% silica and 25% of toxicant.
Useful liquid concentrates include the emulsifiable concentrates, which are homogeneous liquid or paste compositions which are readily dispersed in water or other dispersant, and may consist entirely of the fungicide with a liquid or solid emulsifying agent, or may also contain a liquid carrier such as xylene, heavy aromatic naphthas, isophorone, and other nonvolatile organic solvents. For application, these concentrates are dispersed in water or other liquid carrier, and are normally applied as a spray to the area to be treated.
Other useful formulations for fungicidal applications include simple solutions of the active fungicide in a dispersant in which it is completely soluble at the desired concentration, such as acetone, alkylated naphthalenes, xylene, or other organic solvents. Granular formulations, wherein the fungicide is carried on relatively coarse particles, are of particular utility for aerial distribution or for penetration of cover-crop canopy. Pressurized sprays, typically aerosols wherein the active ingredient is dispersed in finely divided form as a result of vaporization of a low-boiling dispersant solvent carrier, such as the Freons, may also be used. All of those techniques for formulating and applying fungicides are well known in the art.
The percentages by weight of the fungicide may vary according to the manner in which the composition is to be applied and the particular type of formulation, but in general comprise 0.5% to 95% of the toxicant by weight of the fungicidal composition.
The fungicidal compositions may be formulated and applied with other active ingredients, including other fungicides, insecticides, nematocides, bactericides, plant-growth regulators, fertilizers, etc.
A further understanding of the invention can be had in the following non-limiting Examples. Wherein, unless expressly stated to the contrary, all temperature ranges refer to the Centigrade system and the term "ambient" or "room temperature" refers to about 20°C to about 25°C The term "percent" refers to gram moles. The term "equivalent" refers to a quantity of reagent equal in moles, to the moles of the preceding or succeeding reagent recited in that example in terms of finite moles or finite weight or volume. Also, unless expressly stated to the contrary, geometric isomer and racemic mixtures are used as starting materials and correspondingly, isomer mixtures are obtained as products.
